[Rcpp-devel] Advice on installing CHOLMOD/Suitesparse

[Douglas Bates]

Somehow you have obtained a buggy version of RcppEigen_0.3.1.tar.gz

I just downloaded that file from a CRAN mirror and this version has
the file RcppEigen/inst/include/Eigen/CholmodSupport starting with

#ifndef EIGEN_CHOLMODSUPPORT_MODULE_H
#define EIGEN_CHOLMODSUPPORT_MODULE_H

#include "SparseCore"

#include "src/Core/util/DisableStupidWarnings.h"

extern "C" {
  #include <RcppEigenCholmod.h>
}

Check your copy of that file.  It looks like it has #include
<cholmod.h> instead of #include <RcppEigenCholmod.h>

It is quite possible that you would have gotten a buggy version if you
checked out a copy of the SVN archive at some random time.  Making
such a change is something I would tend to forget until tests started
failing.
